Shared Lives

Each of us shares our bodies with numerous microbes. The estimated ratio of microbes to human cells is 10 to one. Microbes contribute to metabolism and healthy function of the body. Evidence is growing that lifestyles (diet and perhaps exercise and sleep) determines the mix and amounts of microbes. Antibiotics have a major impact upon the bacteria that invade as well as those that inhabit our bodies. There are so many things we don't know about this aspect of health, as well as health in general.
